I heard a gold crown lasts longer. Is that right?

Among the various crown materials, a gold crown does tend to last a long time, thanks to the ductility of gold - the property of deforming rather than fracturing under force - which means it rarely breaks, and to its excellent fit, meaning how precisely it meets the tooth. But it is hard to say it always lasts longer than the zirconia crowns that are popular now. Zirconia has less ductility but high strength, so it does not break easily, and it has better biocompatibility than gold. Many factors affect how long a crown lasts, and how the treatment is carried out matters more than the material. In short, gold is not always the best choice - select the material that suits your situation in consultation with your dentist.
